How do we know what dinosaurs looked like?

Sometimes we have other evidence of dinosaur feathers, such as marks on the forearm bones of Velociraptor which correlate to the ‘quill knobs’ where the ligaments of flight feathers attach on pigeons today.
It’s this feature in Velociraptor fossils from Mongolia that led experts to assume all dromaeosaurs had small ‘wings’ on their forearms – a feature now confirmed by the Chinese fossil of another new dromaeosaur called Zhenyuanlong, described in 2015 by scientists including Dr Stephen Brusatte at the University of Edinburgh. | Science Focus [HT: The Dog @ Dinosaurs - Maggie's Farm]
